BREAST-ROLL TRANSFER MECHANISM FOR FOURDRINIER PAPER-MAKING MA- GHINES.

Application filed July 23, 1924, Serial This invention relates to apaper making machine and more particularly to the breast roll end of aFourdrinier wherein the table is adapted to be moved transversely out ofb the side of the machine into a position to permit the wire tobe'replaced by a new one or repaired as the case may be.

It is an object of this invention to provide an improved Fourdrinierbreast roll mounting and mechanisms whereby the breast roll and itsbearings may be transferred as a unit onto the table for removaltherewith when it becomes necessary to replace the Fourdrinier wire.

It is also an object of the invention to provide a breast roll mountingfor a Fourdrinier, said mounting being arranged to permit the breastroll and its hearings to be removed as a unit and transferred over atemporary support onto a bracket mounted on the table whereby the breastroll may be moved out of the side of the machine with the table topermit replacement of the Fourdrinier wire.

It is an important object of this invention to provide a simple andimproved breast roll mounting for the Fourdrinier end of a paper makingmachine, said mounting be-,

ing arranged to permit release of the breast roll so that the same maybe rolled across a removable bridge onto a table support for removalwith the table to permit replacement of the Fourdrinier wire.

Other and further important objects of this invention will be apparentfrom the disclosures in the specification and drawings.

The'invention (in a preferred form) is illustrated in the drawings andhereinafter more fully described.

On the drawings:

Figure 1 is a fragmentary front side elevation of the breast roll end ofa Four-drinier machine illustrating the improved breast roll mountingembodying the principles of this invention.

Figure 2 is afragmentary sectional view taken on line 2-2 of Figure 1.

Figure 3 is a fragmentary front side view similar to Figure 1 showingthe breast roll No. 727,638. Renewed April 29, 1926.

removed from its mounting and supported on the table brackets.

Figure 4 is a top plan view of the bridge bar and the table bracket.

As shown on the drawings:

The reference numeral 1 indicates the base I-beams which form a basesection for the Fourdrinier end of a paper making machine. Mounted onone end of the base section (although not shown) is a head or flow boxto the sides of which are secured the ends of supporting st ips orsprings 2. The outer end of each spring 2 is secured to a breast rollsupporting bracket 3 of semicircular shape and having the lower end 4rigidly mounted upon a pair of upright wooden strips or springs 5. Thelower ends of the springs 5 are secured to base pieces 6 bolted to thebase members 1. The lower end 4 of each supporting bracket 3 is providedwith an integral shelf plate 7 through which anadjusting screw 8projects. Openings are provided in the side flanges of the lower end 4of each bracket 3 to removably receive retaining pins 9. Attached to theupper portion of each supporting bracket 3 by means of a bolt 10 is acurved clamp or arm 11.

A breast roll 12 forms part of the machine and is provided with journalswhich are engaged in bearings 13. Each breast roll bearing 13 has formedthereon aperipheral gear 14. A squared shank or stub shaft 15 1s formedon each bearing 13 to receive the apertured head'of a wrench handle orcrank arm.

A set-screw 28 is provided in each bearing 13 for the purpose of lockingthe hearings to the journals of the breast roll to permit rolling of thebreast roll together with the bearings as a unit when crank arms areengaged on the squared stub shaft 15 of the bearings.

Forming part of the Fourdrinier is a table 16 upon which the table rolls17 are supported. The table 16 together with the table rolls 17 form aunit of a type which is adapted to be moved out through the front sideof the Fourdrinier section to permit replacegrally formed on the bracket18 at the sides of the plate 20 and removable support pins 24.

When it is desired-to replace the Four- --drinier wire, a bridgebeam'25is supported in place on each side of the machine by means of thepins 9 and the pins 24. The brid ebea-ms 25 span the space between thebrac et 18 and the lower end 4 of the supporting bracket 3. The screws 8and 21 are adapted to be adjusted to adjust the bridge beams. Formed onthe top of each bridge beam is a row of teeth to form a rack 26 forco-action with the teeth of. the gear 14. The teeth 19 on the brackets18 afford a continuation of the rack 26. z I

The operation is as follows:.

When'the Fourdrinier wire is to be removed from the machine the bridgebeams 25 are mounted in place as illustrated in Fig: ure 1 supported bythe pins 9 and 24. Adjustment of the bridge beams is accomplished byadjusting until the bridge beams are properly positioned connecting thetable rails 16 with the A lower ends 4 of the supporting brackets 3. Thelocking set screws 28 are adjusted to lock the bearings to the journalsof the roll.

The bolts 10 are next loosened and. the clamps '11 are pushed upwardlyand secured in the release position of Figure 3 thereby releasing thebreast roll 12 and its supporting bearings 13. By applying crank arms tothe squared stub shafts 15 of the breast roll bearings the breast rolltogether with its bearings is rolled out of the supporting brackets 3 asa unit with the gear teeth 14 meshing with the rack teeth 26 and therack teeth 19*. The breast roll 12 and its bearings 13 is thus rolledacross the bridge beams 25 as a unit onto the brackets 18 as illustratedin Fig. 3. After-the bridge beams are" removed wedge members or stopdogs 27 are engaged behind the pins 24 and beneath the.

bearings 13 of the breast roll 12. The breast roll unit is thus held inplace on the brackets 18 after which the table carrying the breast rollunit are moved as a unit out through the front side of the Fourdriniersection to permit a new wire to be mounted implace inthe machine.

While set screws 28 are described as a means for locking the bearings tothe journalsof the breast roll, pins or. any other suitable lockingmeans may be used.

I am aware that many changes may be made, and numerous details ofconstruction may be varied through a wide range without the screws 8 and21' respectively departing from the principles of this invention, and Itherefore do not purpose limit.- ing the patent granted hereon,otherwise than necessitated by the prior art.
